LYLE K SNELIa OF DETROIT, MICHIGAN, ASSIGNJB TO CADILLAC MGTOR CAR COMPANY,

0F DETROIT, MICHIGAN, A CORBORATION 0F MICHIGAN.-

l Moron-vaincra Y To all 'whom t may concern:

' Be it known that I, LYLE K. SNELL, a citizen of the United States, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specication.

This invention relates to improvements in motor vehicles and more particularly to spring oilers therefor.

One of the objects of the invention is to devise an eiiicient lubricatorof simple construction which may be readily applied to a vehicle spring.

Another object of the invention is to devise a lubricator for vehicle springs which shall be practically dust proof.

Another object of the invention is to provide a lubricator which shall clamp the several leaves of the spring against lateral movement.

Another object of the invention is to provide a spring lubricator which may contain an abundant supply of lubricant and which shall be of durable construction and of neat appearance. The various objects, purposes, constructions and principles involved, will more clearly appear from the following description, taken in connection with the accompanying drawings which form a part of this specification and in which:

Figure 1, is a side elevation of a section of a vehicle spring showing a form of the invention applied thereto.

' Fig. 2, is an enlarged transverse vertical sectional view on the line 2 2, Fig. 1.

Fig. 3, is a vertical longitudinal sectional view on the line 3 3, Fig. 2.

Fig. 4, is an enlarged View looking at the under-side of a section of the spring having the invention applied thereto.

Fig. 5, is a side elevation of a portion of a spring curved in the reverse direction to that shown in Fig. 1, and showing a modified form of the invention lapplied thereto.

Fig. 6, is an enlarged transverse vertical sectional view onA the line 6-6, Fig. 5. Y

Fig. 7, is a longitudinal vertical sectional view on the line T4-7, Fig. 6.

Fig. 8, is an enlarged view showing the underside of a section of a spring with the modified form of the invention Vapplied thereto.

Referring tothe drawings, particularly Figs. 1 to 4, inclusive, 10 illustrates aV p0rtion of a section of an upwardly curved i Specicationof Letters'Patent. Patntde. 16,1919.. Application filed March 2, 1917. Serial No. 151,886. i' y' Yma laminated leaf spring, the leaves of which are adapted to be secured .together by the arrangement midway between the ends of 4a shackle plate 11, and bolts, 12.

Lubricating devices `which willv be presently more particularly described may be suitably arranged on the spring at oppo.

site sides of the shackle.

Each of the lubricating devices comprises a U shape casing member 13, preferably stamped or forged out of sheet steel. The casing member is adapted to have struck upl or formed therein intermediate its width, a passage or channel 14, extending from one extremity to the other.

Ysoy

A defiector plate 15 is adapted tobe arranged across the bottom of the channel 14, in the transverse portion or top 17, of the casing member, with its opposite edgesflS, adjacent the top of the side channels 1-9, which are formed inthe downwardly 'extending branches 2O ofthe casing member, The deiiector plate 15,may be suitably secured in position in the casing member as by welding.Y Y.

rihe casing member is adaptedv tovbe arranged over and slipped downwardly into position over a section of the spring 10. It will'be noted that a port 21 is formed in the top 17, and an oil reservoir 22,. is provided with a cap 23, and is adapted to be secured over this port, as bythreads 24. The member l13 is provided with flanged portions 25, which areadapted to extend parallel; to the adjacent edges and surfaces of the various portions of the spring onwhich it is mounted. An absorbent material, l'such as in the form of wicxs 26, may beaiiangedrbetween the sides 2'?, of the spring leaves and the outer wall of the channel 1 The casing member 13 may be secured in position against lateral or longitudinal movement relative to the spring leaves, by means of a plate 28, y.which is adapted to extend across vthe entire bottom of the casing-member 13, and to be secured to the bottom leaf 29 of the spring as bya rivet 30. The opposite ends of the plate 28, maybe struck up to form a pair of bosses 31, and-boltsBQ/ may be passed through lugs 33 formed at the lower extremities of the branches 2O of the mem- Y elusive, it will be noted that a modified form of oiling device is shown applied to a downwardly curved section of a laminated leaf spring. The general form of the casing member of this spring device is very simiv lar to that described in connection with the other figures; it, however, being arranged on the spring in reverse relation to that of the previously described device.

It will also be noted that the modified forni of casing member 13 is not provided with a port in its transversely extending portion; the oil reservoir in the modified construction is arranged at the opposite end of the casing member.

A plate 28 having down turned ends forming bosses 31 is adapted to be arranged across the upper extremities of the branches 20 of the casing member 13 for closing the entire upper portion of this member. Suitably arranged between the bosses 31 of the plate 2S and in spaced relation thereto, is a deflector plate 15. A spacing collar 85 may be inserted between plates 28 and 15 and these parts may be secured in position by a rivet 36 passing through the upper leaf of the spring and these two plates and the spacing collar. A pair of bolts 32, and their Complementary nuts Connect the branches 20 of the casing member with the bosses 31 of the plates 28.

It will be noted that the plate 28 is formed with port 21 over which is secured the reservoir 22.

With the latter described construction, lubricant is fed through the port 21 over the deflector plate 15 to the absorbent material 26, and any surplus oil which is not suspended by the wick will be collected in the reservoir 37 which is formed in the bottom of the member 13.

While I have described and will specifically claini what I deem to be a preferred embodiment of my invention, it will be obvious to those skilled in the art that various modifications and changes may be made without departing from the spirit and scope thereof.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1.
